Cannot reply to a meeting invite: "You are neither an organizer nor an attendee of this scheduled item."

When a meeting invite from Outlook is sent to a mailing list, I receive the invitation, but I cannot action the meeting invite: I cannot confirm or reject. The message in the invite reads:

You are neither an organizer nor an attendee of this scheduled item.

I’ve read previous threads where the issue was reported back in version 5.x but it seems that as per my version 7.1.30794 it is still an issue.

If I am directly invited I don’t have any problems, only when the meeting invite is sent to a mailing list.

Do you have any solution for the issue? Thanks very much in advance!

PS. It was constantly mentioned in previous threads that you can still manually copy the meeting invite to your calendar, but that also means manually maintaining any updates or cancellations.
